The Voyage of H.M.S. Challenger 1873-1876. Narrative Vol. I. First Part. Chapter I

The deep-sea investigations conducted on board H.M. Ships " Lightning," "Porcupine," and" Shearwater," in the years 1868, 1869, 1870 and 1871, and the subsequent correspondence between the Lords Commissioners of the Admiralty, the Council of the Roya...

Investigating the March 28th 1875 and the September 20th 1920 earthquakes/tsunamis of the Southern Vanuatu arc, offshore Loyalty Islands, New Caledoni...

New Caledonia's Loyalty Islands are located in the southwest region of the Pacific ocean in the highly seismogenic southern Vanuatu subduction zone and therefore may be subject to devastating local tsunamis. Over the past 150 years, two large tsunami...

Sediment transport in coastal waters

Globally, while land erosion has increased in the last decades, sediment input to the ocean has decreased. Sediment transport and distribution at the land-ocean interface has huge impacts on morphodynamics of estuaries, deltas and coastal zones, on w...

Considering reefscape configuration and composition in biophysical models advance seascape genetics

Previous seascape genetics studies have emphasized the role of ocean currents and geographic distances to explain the genetic structure of marine species, but the role of benthic habitat has been more rarely considered. Here, we compared the populati...

Quelle stratégie de recherche pour une meilleure conservation de la biodiversité terrestre dans les îles tropicales ultramarines françaises ?

Les îles tropicales de l'Outre-mer français, réparties dans 11 territoires situés dans trois océans (Atlantique, Indien et Pacifique), concentrent, sur des superficies terrestres restreintes, une diversité d'espèces et d'habitats exceptionnell...

Acclimatization of massive reef-building corals to consecutive heatwaves

Reef-building corals typically live close to the upper limits of their thermal tolerance and even small increases in summer water temperatures can lead to bleaching and mortality. Projections of coral reef futures based on forecasts of ocean temperat...

Enjeux, spécificités et perspectives de la gestion intégrée du littoral dans l'espace insulaire français du sud-ouest Pacifique

L'article présente une analyse de la gestion intégrée du littoral dans l'espace insulaire français du sud-ouest Pacifique. Après avoir décrit le contexte régional et les enjeux face aux problèmes induits par le réchauffement climatique, il a...

Eocene pre- and syn-obduction tectonics in New Caledonia (Southwest Pacific), a case for oblique subduction, transcurrent tectonics and oroclinal bend...

The structural analysis of the metamorphic belt and allochthonous terranes, which represent the lower and upper plates of the Eocene subduction/obduction complex of New Caledonia respectively, unravels a multi-step evolution. At subduction inception,...

La Mer : hommes - richesses - enjeux

Chapters in Volume 1: - Law of the sea and international straits - Trends in the French merchant fleet - International shipping - Safety and rescue at sea, the case of yachting - Marine research and economic development - The respectiv...

The East Caledonian Current : a case example for the intercomparison between AltiKa and in situ measurements in a boundary current

This paper presents an assessment of SARAL/AltiKa satellite altimeter for the monitoring of a tropical western boundary current in the southwestern Pacific Ocean: the East Caledonian Current. We compare surface geostrophic current estimates obtained ...
